Degassing

Gasoline Product Pipeline Degassing

A West Coast oil company needed to purge 20 miles of pipeline with crude and hydrogen sulfide vapors. The oil company needed a solution to vapor degas this large volume of crude and H2S vapor from this pipeline to allow pipeline repairs.
Midwest Refinery Turnaround Services

A Midwest refinery contracted Envent to provide degassing and vapor control services. The refinery planned a major turnaround and had multiple critical-path process units that needed industrial degassing and industrial vapor control services for safe entry into process vessels.
Southern California Refinery Excess Fuel Gas Elimination Project

We believe Safety is No Accident.
Port Arthur Refinery, Flareless Hydrocracker Turnaround

Port Arthur refinery customer had to complete a flareless turnaround involving their Hydrocracker Unit. Envent mobilized three EMECS-42 thermal oxidizers, two ESCRUB-6000 recirculating scrubbers, and all associated safety equipment to complete the decommissioning.
Northern California Refinery, Sour Naptha Degas

In mid April 2016 a Northern California Refinery discovered a seal leak on a 145 ft. diameter x 75 ft. tall above ground external floating roof storage tank that was in Sour Naptha service. Due to the sour nature of the product in the tank, this seal leak presented substantial safety and environmental hazards to any personnel working at the refinery as well as to the surrounding community.
Emergency Response, Butadiene Pipeline Degassing Project, Texas.

Emergency Response Call-out to depressurize a 13 mile long section of 12 inch pipeline containing butadiene. Required to line depressurize from 250 PSIG to 0 PSIG. Envent engineered and was on-site within 2 hours, in the middle of the night.
Thermal Oxidizer vs IC Engine

A customer indicated a serious incident that had taken place in the facility a few weeks earlier while a degassing company was performing vapor control on a gasoline storage tank.
Tank Roof Collapse

Leave tank cleaning to the experts. Leave tank degassing to Envent. Among several other vapor service lines, Envent degasses tanks. Being a tank degassing specialist, Envent does not dilute its attention to detail in an effort to capture more work scope and therefore more project revenue.
Pyrophoric Tank Degassing

Envent brings experience to the project site. With experience comes the knowledge to ask the right questions.
Emergency Pipeline Degas

During the re-commissioning of the pipeline a leak was detected. The leak was isolated between two stations roughly 16 miles of pipeline. In total 12,000 barrels of propane needed to be combusted as quickly as possible.
EICE – Naphtha Tank Degas

A tank farm customer requested Envent degas a 123 foot diameter naphtha tank. The tank farm was able to continue operations around the tank while degassing was in progress due to the small footprint of the EICE.
Southern California, Sour Tank Inert Degas Operations

A nationwide petroleum company had an API inspection deadline on a 110’ diameter External Floating Roof Tank containing sour crude product. There was an acute hazard in the tank for pyrophoric materials, materials which ignite in the presence of oxygen without an ignition source. The petroleum company understood that they would need an all-star team to degas, clean, and inspect this tank.
